extension cord must also contain a ground wire and
plug pin.
27. Wear proper clothing, DO NOT wear loose clothing,
gloves, neckties, or jewelry. These items can get
caught in the machine during operations and pull
the operator into the moving parts. Users must
wear a protective cover on their hair, if the hair is
long, to prevent it from contacting any moving parts.
GENERAL SAFETY
1. Serious personal injury may occur if normal safety
precautions are overlooked or ignored. Accidents
are frequently caused by lack of familiarity or failure
to pay attention. Obtain advice from supervisor,
instructor, or another qualified individual who is
familiar with this machine and its operations.
6. Safety decals are on this machine to warn and
direct you to how to protect yourself or visitors from
personal injury. These decals MUST be maintained
so that they are legible. REPLACE decals that are
not legible.
7. DO NOT leave the unit plugged into the electrical
outlet. Unplug the unit from the outlet when not in
use and before servicing, performing maintenance
tasks, or cleaning.

WARNING
WARNING
9. DO NOT handle the plug or bench grinder with
wet hands.
10. USE accessories only recommended by Steel City.
11. DO NOT pull the bench grinder by the power cord.
NEVER allow the power cord to come in contact
with sharp edges, hot surfaces, oil or grease.
4. TO REDUCE the risk of electrical shock. DO
NOT use this machine outdoors. DO NOT
expose to rain or moisture. Store indoors in a
dry area.
12. DO NOT unplug the bench grinder by pulling on the
power cord. ALWAYS grasp the plug, not the cord.
5. STOP using this machine, if at any time you experience difficulties in performing any operation.
Contact your supervisor, instructor or machine service center immediately.
12
13. REPLACE a damaged cord immediately. DO NOT
use a damaged cord or plug. DO NOT use If the
bench grinder is not operating properly, or has been
damaged, left outdoors or has been in contact with
water.
14. DO NOT use the bench grinder as a toy. DO NOT
use near or around children.
19. DO NOT stand in front of the bench grinder when
starting it. Stand to one side and turn the bench
grinder ON. Wait at the side for one minute until the
grinder comes up to full speed. There is always a
possibility that debris from a damaged grinding
wheel may be discharged toward the operator.
15. ALWAYS wear eye protection. The operation of any
grinder can result in debris being thrown into your
eyes, causing severe eye damage. Everyday
glasses are not safety glasses. Wear safety glasses
that comply with ANSI standard Z87.1
20. Sparks and debris are normally produced during
grinding operations. BE SURE that there are not
any flammable materials in the vicinity. Frequently
clean grinding dust from the back of bench grinder.
16. ALWAYS use the eye shields and wheel guards
provided with the grinder.
17. REPLACE a cracked or damaged grinding wheel
immediately. A damaged wheel can discharge
debris at a high velocity towards the operator.
Carefully handle the grinding wheel since it is abrasive. Prior to replacing a grinding wheel, check it
for cracks. Do not remove the labels from a grinding
wheel. Tighten the spindle nut just enough to hold
the grinding wheel firmly to the bench grinder. Do
not overtighten, excessive clamping force can
damage the grinding wheel. Only use the wheel
flanges provided with the grinder. When selecting a
replacement grinding wheel, verify that the grinding
wheel has a higher RPM rating than the maximum
RPM of the bench grinder.
21. NEVER force the workpiece against a grinding
wheel, especially if the wheel is cold. Apply the
workpiece slowly, allowing the grinding wheel an
opportunity to warm up. This will minimize the
chance of wheel breakage. DO NOT grind using the
sides of the grinding wheels. DO NOT apply coolant
directly to the grinding wheel.
22. NEVER use the bench grinder with the wheel
guards removed.
23. ALWAYS keep the tool rests firmly tightened.
24. ALWAYS use the supplied wheel dresser to resurface the grinding wheel faces.
18. BE AWARE that the diameter of a grinding wheel
will decrease with use. Adjust the tool rests and
spark arrestors to maintain a distance of 1/16” from
the wheel.
ELECTRICAL REQUIREMENTS
TO PREVENT electrical shock, follow all electrical and
safety codes, including the National Electrical Code
(NEC) and the Occupational Safety and Health
Regulations (OSHA). All electrical connections and
wiring should be made by qualified personnel only.
DO NOT connect the machine to the power source
before you have completed the set up process.
TO REDUCE the risk of electrical shock, DO NOT use
machine outdoors. DO NOT expose to rain or moisture. Store indoors in a dry area.
This motor in this machine is designed to run at 120V.
DO NOT connect the machine to the power source until
instructed to do so.
GROUNDING INSTRUCTIONS
!
WARNING
If a plug is provided with your machine DO NOT modify
the plug. If it will not fit your electrical receptacle, have
a qualified electrician install the proper connections to
meet all electrical codes local and state. All connections
must also adhere to all of OSHA mandates.
This machine MUST BE GROUNDED while in use to
protect the operator from electric shock.
In the event of a malfunction or breakdown, GROUNDING provides the path of least resistance for electric
current and reduces the risk of electric shock. The plug
MUST be plugged into a matching electrical receptacle
that is properly installed and grounded in accordance
with ALL local codes and ordinances.
IMPROPER ELECTRICAL CONNECTION of the equipment-grounding conductor can result in risk of electric
shock. The conductor with the green insulation (with or
without yellow stripes) is the equipment-grounding conductor. DO NOT connect the equipment-grounding conductor to a live terminal.
13
Check with a qualified electrician or service personnel if
you do not completely understand the grounding
instructions, or if you are not sure the tool is properly
grounded.
The motor supplied with your machine is a 120 volt,
60 hertz, single phase motor. Never connect the green
or ground wire to a live terminal.
A machine with a 120 volt plug should only be connected to an outlet having the same configuration as the
plug.
Fig. A
EXTENSION CORDS
!
WARNING
To reduce the risk of fire or electrical shock, use the
proper gauge of extension cord. When using an
extension cord, be sure to use one heavy enough to
carry the current your machine will draw.
Fig. B
The smaller the gauge-number, the larger the diameter
of the extension cord is. If in doubt of the proper size of
an extension cord, use a shorter and thicker cord. An
undersized cord will cause a drop in line voltage resulting in a loss of power and overheating.
!
CAUTION
USE ONLY a 3-wire extension cord that has a 3-prong
grounding plug and a 3-pole receptacle that accepts the
machine’s plug.
If you are using an extension cord outdoors, be sure it
is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.
Make certain the extension cord is properly sized, and
in good electrical condition. Always replace a worn or
damaged extension cord immediately or have it
repaired by a qualified person before using it.
PLUGS/RECEPTACLES
!
Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.

Fig. 12
A
A
1. Adjust the right side tool rest (A) until it is in the
level horizontal position as shown and 1/16” away
from the grinding wheel. SEE FIG. 11.
2. Turn ON the bench grinder, then turn the variable
speed knob clockwise until solid resistance is felt.
Let the grinding wheel get up to a steady speed for
one minute.
B
6. Place a crescent wrench (A) (not included) on the
arbor hex nut. Place the box end of the custom
wrench (B) onto the flats of the arbor shaft. SEE
FIG. 12.
3. After the grinding wheel has gotten to a steady
speed, place the wheel dresser (B) flat on the tool
rest with diamond surface facing the grinding wheel.
4. Firmly hold onto the wheel dresser handle.
NOTE: The left hand arbor hex nut is is a left hand
thread and is loosened by rotating it counter-clockwise.
5. Move the wheel dresser forward until the diamond
surface comes in contact with the grinding wheel
(C). After contact has been made, slide the wheel
dresser side to side across the tool rest to DRESS
the grinding wheel until the edges are square and
the surface is clean.
7. Remove the outer wheel flange and then the abrasive wheel from the arbor shaft.
CAUTION: The new abrasive wheel must have a higher
RPM rating than the grinder (3450 RPM). The new
abrasive wheel must have the correct outer wheel
diameter and bore diameter as the original wheel. The
label on the abrasive wheel must stay on.
6. After the operator has completed dressing the
grinding wheel, turn OFF the bench grinder and let
the grinding wheel come to a complete stop.
8. Replace the abrasive wheel, outer wheel flange,
and arbor hex nut. Remember(1) the left arbor hex
nut is a left hand thread and is tightened by rotating
it counter-clockwise (2) the right arbor hex nut is a
right hand thread and is tightened by rotating it
clockwise.
7. Inspect the grinding wheel for any damage.
8. The grinding wheel may now be slightly smaller in
diameter after dressing. Readjust the tool rests and
spark arrestors to maintain a 1/16” clearance to the
grinding wheel.
18
CAUTION: Do not over-tighten the arbor hex nut as this
may damage the abrasive wheel and cause serious
injury.
allow the arbor hex nut to tighten correctly. These spacers are identical to each other.
One spacer should always go onto the arbor shaft first.
The second spacer, if needed, will go on next to the
arbor hex nut. Always use the wheel flanges that come
with the grinder (for wire wheel or buffing wheel).
NOTE: A wire wheel or a buffing wheel can be used
with your grinder. Depending on the thickness of the
wheel, you will need to add one or more spacers to
OPERATIONS
!
The bench grinder is designed for hand held grinding,
sharpening, and cleaning operations.
